Introducing Sonata — the new open source platform for CHERIoT development
summary
Sonata is an open source FPGA development platform that ships a CHERIoT-enabled Ibex core with I2C, SPI, GPIO, PWM, UART and DMA on an Artix-7 FPGA board (Sonata by NewAE) and is released under Apache 2.0. The demo shows a compromised JavaScript interpreter reading a C static secret when run flat, then the same binary placed in separate CHERI compartments cannot access the secret thanks to capability checks. Firmware uses a drag‑drop USB flow and Nyx/CherOS tooling; 1003 boards shipped.
